About this conversion
This page converts Celsius (°C) into Rankine (°R), two scales used to measure temperature.
Celsius to Rankine conversions come up in science, engineering, weather reporting, and historical references, depending on which scale is in use.
The formula is °R = (°C × 9/5) + 491.67, a linear equation that accounts for both the scale factor and the zero-point offset between the two scales.
The conversion is exact: it uses fixed constants defined by the relationship between the two scales, not a measured or approximate factor.
Celsius is a temperature scale based on the freezing and boiling points of water. Rankine is an absolute temperature scale that uses Fahrenheit-sized degrees.
